Chauvin Arnoux p03652921 SK17 air sensor, -50...+600°C content_copy

The Chauvin Arnoux SK17 is a K-type thermocouple probe, specifically designed for measuring air temperatures in industrial and technical applications. The device enables precise detection of ambient temperatures in the range of -50 °C to +600 °C. The sensor is protected within a metal sheath with a diameter of 8.5 mm, ensuring robust and long-lasting operation even under demanding conditions. The probe features a handle and a spiral cable, facilitating handling and positioning during measurement.

Applications

The SK17 is suitable for applications requiring the measurement of air flows or temperatures in open environments. Typical use cases include monitoring ventilation and climate control systems, temperature control in production processes, and measurements in heating and cooling systems. The high temperature limit of +600 °C also makes it suitable for high-temperature applications, such as in metal processing or monitoring furnace exhaust gases.

Functions and Features in Detail

The probe operates as a K-thermocouple, a widely used and reliable measurement principle for temperature detection. Measurement is contactless with the air, where the sensor within the metal sheath buffers thermal stress and protects against mechanical damage. The response time is 3 seconds, enabling rapid reaction to temperature changes. The total length of the probe is 130 mm, with the sensing part having a diameter of 6 mm. The spiral cable provides a flexible connection and prevents tangling during frequent use.

Technology Explained Simply

A K-thermocouple consists of two different metal conductors joined at one point. When there is a temperature difference between this point and a reference point, a small electrical voltage is generated, proportional to the temperature difference. This voltage is evaluated by a measuring device and converted into a temperature reading. The metal sheath of the SK17 protects the sensitive sensor and ensures uniform heat transfer, maintaining measurement accuracy.

Compatibility and Accessories

The SK17 is designed for use with measuring instruments that support K-type thermocouples. Connection is made via the spiral cable, which is attached to an appropriate input on the measuring device. The probe is intended as a single component and must be combined with a suitable measuring instrument.

Installation and Mounting

Installation is performed by placing the sensor directly into the air stream to be measured. The metal sheath allows for secure mounting, for example by screwing or securing in a suitable housing. The spiral cable can be routed flexibly to connect to the measuring device. No additional mounting accessories are required, as the probe is already equipped with a handle and cable.

Operational Advantages

The combination of fast response time, wide temperature range, and mechanical robustness makes the SK17 a reliable tool for continuous temperature measurements. The metal sheath protects the sensor from contamination and mechanical stress, increasing its service life. The easy handling provided by the handle and spiral cable facilitates use in mobile or frequently changing measurement scenarios. The probe is designed for industrial environments where high demands on accuracy and reliability are placed.
